Paul, that reminds me of a website offering pretty much that, a rent-a-pet service. It may have been that same scam artist Simon Brodie that launched it. Basically if you thought you were too busy to have a pet but loved animals you could buy in and just share that pet at times convenient to you! Not sure if Savannahs were offered though...
Wow - I never heard of it - rent-a-pet? is that like rent-a-child
